Paeonies grow best in a light sandy loam, and need but little attention - digging round and manuring in the winter, and some care in tying them up neatly in the spring, being all they require. They soon increase, but it is injurious to divide the roots too often, as the constitution of the plant is by this means weakened, and they generally take some time to recover their usual vigour; nor should they be dug up and removed frequently, as this is apt to check their growth for a season at least.
